National Water Week
A national celebration of water
National Water Week makes a splash across Australia in October each year. This year, National Water Week will run from 19-25 October 2026.
National Water Week makes a splash across Australia each year by inspiring communities and organisations to work together on water issues and future fixes.
National Water Week reminds everyone that water must be used wisely – and celebrates water innovation and achievements supporting Australia’s sustainable future.
